In order to clarify the dynamic interfacial force between a slider and disk in the nanometer flying height region, we have measured the dynamic adhesion force when spherical sliders, with radii of 1 and 2mm, collide with smooth magnetic disks with 0, 1, 2, and 3nm thick lubricant layers. From the measured slider velocity, we calculate the relationship between acceleration (acting force) and displacement. We find that a strong adhesion force, observed at zero lubricant, vanishes at 1nm thick lubricant with UV bonding. As the mobile lubricant thickness increases, we observe a clear dynamic adhesion force at the instant of separation. These results imply that the dynamic adhesion force originates from meniscus formation.
